UserBenchmark is a computer hardware benchmarking and comparison website. It allows users to test the performance of CPUs, GPUs, SSDs, HDDs, RAM, and USB storage devices and compare their results with those submitted by other users.^[1]

The service originated in 2011 as whoratesit, a social-rating website covering subjects including movies, books, software, and computer hardware. It was rebranded as UserBenchmark in 2013 and subsequently became primarily focused on computer hardware benchmarking.^[1]

UserBenchmark became widely used for quick comparisons and diagnosis of individual computers because of its large database of user-submitted benchmark results. It has also become controversial among computer-hardware enthusiasts and reviewers, particularly because of its CPU scoring methodology, editorial commentary concerning AMD, and differences between its aggregate rankings and those produced by independent hardware-review publications.^[2]

UserBenchmark originated in 2011 as a website called whoratesit. According to Tom's Hardware, the original service functioned as a social platform for rating and comparing a variety of subjects, including movies, books, computer software, and computer hardware.^[1]

The original service was therefore broader than the later UserBenchmark website, which became primarily concerned with computer hardware performance.

In 2013, whoratesit was rebranded as UserBenchmark. The service shifted its focus toward collecting performance measurements from users' computers and comparing those measurements across hardware models.^[1]

The resulting service used a downloadable benchmarking application that tested components on a user's computer and uploaded the results to the UserBenchmark website.

By 2014, UserBenchmark was publicly documented as a computer hardware benchmarking service. Contemporary computer-hardware discussions described a downloadable application that tested CPUs, GPUs and storage devices and automatically uploaded results to UserBenchmark's database.^[3]

A 2014 software archive listed UserBenchMark version 2.6 as a freeware Windows application capable of testing storage, CPU and GPU performance and uploading reports to UserBenchmark.com.^[4]

The service differed from conventional hardware-review benchmarks by relying on a large number of results submitted by users rather than testing a fixed selection of hardware under controlled laboratory conditions.

During the mid-to-late 2010s, UserBenchmark expanded its database to cover CPUs, GPUs, SSDs, HDDs, RAM and USB storage devices.

The service provided both individual system reports and aggregate product comparisons. Individual reports were intended to help users determine whether their own hardware was performing within the expected range for the same hardware.

Because results were submitted from individual computers, measurements could be affected by factors such as cooling, power settings, memory configuration, drivers, background applications and other system conditions.

The large number of UserBenchmark submissions also made the service a source of information about unreleased hardware. The benchmark program allows users to upload their hardware score results to the website. This made the website a frequent source of unreleased hardware leaks. For example, benchmarks of recent CPU engineering samples can be searched for on the website using search queries AMD Eng Sample^[5] and Intel 0000^[6] then sorting by new. Pre-release results for processors and graphics cards from manufacturers including AMD, Intel and NVIDIA have appeared in the UserBenchmark database before the products' official launches. Technology publications have periodically reported on such results as hardware leaks.

In July 2019, UserBenchmark changed the weighting used to calculate its overall CPU performance index following the introduction of AMD's Zen 2 architecture and Ryzen 3000 processors.^[2]

Before the change, UserBenchmark's reported weighting assigned approximately 40% of the score to single-core performance, 50% to quad-core performance and 10% to multi-core performance. The revised system used approximately 40% single-core, 58% quad-core and 2% multi-core weighting.^[2]

UserBenchmark said it had made the change because it believed its previous index was overestimating CPUs with more than eight cores. The company argued that the revised index better represented the workloads it considered relevant to typical desktop users.^[2]

The change attracted considerable criticism because contemporary AMD Ryzen processors generally had more CPU cores and stronger multi-core performance than many competing Intel processors. Critics argued that sharply reducing the contribution of multi-core performance disproportionately affected AMD's higher-core-count processors.

Tom's Hardware highlighted the effect of the weighting system by noting that an Intel Core i3-8100 could rank above the considerably more expensive Intel Core i9-9980XE in UserBenchmark's rankings, despite the latter having 18 cores and 36 threads.^[2]

UserBenchmark subsequently said it would continue to modify its effective-speed indices and acknowledged the criticism surrounding the July 2019 revision.^[2]

UserBenchmark has been accused by hardware enthusiasts of favoring Intel over AMD in its CPU rankings.

The accusations became particularly prominent after the 2019 scoring change. Critics argued that the new weighting system placed relatively little importance on multi-core performance and therefore reduced the apparent advantage of many AMD processors.

UserBenchmark has rejected accusations that its methodology was designed to favor Intel or that it receives outside influence from hardware manufacturers. The company has stated that its scoring system is intended to represent its interpretation of typical consumer workloads.^[2]

There is no established evidence that Intel or another hardware manufacturer paid UserBenchmark to manipulate its rankings. Allegations of such payments have largely originated in online discussions rather than documented evidence.

In addition to numerical benchmark results, UserBenchmark publishes editorial descriptions and commentary about computer hardware.

The site's commentary about AMD products has attracted criticism for what critics regard as unusually negative or confrontational language. Tom's Hardware reported that UserBenchmark became increasingly critical of AMD following the 2019 controversy and subsequently published strongly worded commentary about AMD products and the company's supporters.^[1]

This editorial material has contributed to UserBenchmark's reputation as a controversial source for hardware comparisons.

The controversy resulted in several major online hardware communities restricting or banning UserBenchmark links.

In April 2020, the moderators of the Reddit community r/hardware announced a ban on posts linking to or discussing UserBenchmark. The moderators cited repeated disputes involving the site, its critics, and the resulting lack of productive discussion.^[7]

The ban followed similar restrictions in other hardware-oriented Reddit communities, including communities associated with AMD and Intel.^[7]

These restrictions are evidence of the site's controversial reputation within parts of the enthusiast community, but do not by themselves establish that UserBenchmark's benchmark results are technically invalid.

Another source of criticism is the difference between UserBenchmark's methodology and controlled hardware reviews.

UserBenchmark collects results from computers operated by individual users. Such systems may differ in cooling, motherboard configuration, memory speed, firmware, drivers, operating-system state, power settings and background processes.

As a result, UserBenchmark's aggregate results measure performance across a population of real systems rather than the performance of identical hardware tested under standardized laboratory conditions.

This approach can be useful for determining whether an individual system is performing unusually poorly compared with other systems using the same hardware. However, it makes UserBenchmark's aggregate product rankings difficult to compare directly with controlled benchmarks from specialist hardware-review publications.

In February 2024, UserBenchmark introduced a partial paywall for its benchmarking software.^[1]

The service offered a Pro subscription costing approximately US$10 per year. Users without a subscription could still use the benchmark when free testing slots were available, but the number of free concurrent tests was limited. When no free slots were available, users were required to use the paid service.^[1]

The free testing system also included a three-dimensional CAPTCHA minigame in which users were required to shoot down a number of targets before being allowed to continue.^[1]

The introduction of the paywall generated additional criticism because the site had previously offered its benchmark as a free service.

UserBenchmark.com remained operational through 2025 and 2026. The site continued to provide individual benchmark reports and comparisons for computer hardware.^[8]

Users continued to employ the service for diagnosing underperforming systems. Hardware-support discussions in 2025 continued to link to UserBenchmark results when troubleshooting CPU, GPU and memory performance.^[9]

At the same time, criticism of UserBenchmark remained present in hardware communities, including continued criticism of its CPU rankings and methodology.^[10]

In 2026, a separate website operating at userbenchmark.org began offering a browser-based computer hardware benchmarking service under the UserBenchmark name. The service is distinct from the established UserBenchmark.com website. UserBenchmark.org states that it is independently owned and operated and is not affiliated with, endorsed by, sponsored by, or connected to UserBenchmark.com or any similarly named entity.^[11]

The .org service differs technically from the original UserBenchmark.com benchmark. It operates entirely in a web browser and does not require installation of a benchmarking application. Its published methodology identifies the current measurement revision as 2026.08 and the scoring system as Forensic scoring v2.^[12]

The benchmark consists of three principal stages: sustained CPU throughput, adaptive GPU pressure, and path-tracing convergence. The CPU stage uses parallel browser workers for a 60-second workload. The GPU stage uses an adaptive raster workload, while the final stage progressively renders a fixed path-tracing scene until a specified sample count is reached.^[12]

The site describes the core measurement as free and states that no account is required to perform the benchmark. However, detailed personal reports and access to the lifetime Reports Library are offered as paid products.^[11] This distinction has attracted criticism from some users who expected the benchmark to provide a complete results report without payment.

UserBenchmark.org's website has also changed its presentation and methodology during 2026. Its current website describes the service as a "free" online CPU and GPU benchmark and advertises browser-based measurement, while its methodology documentation emphasizes measurement provenance, sample counts and evidence confidence.^[13][12]

The service's documentation also acknowledges limitations of browser-based testing. It states that a browser cannot directly read hardware temperature, voltage, package power, fan speed or exact hardware-utilization sensors, and that observed performance decay can have multiple possible causes.^[12]

UserBenchmark.org is also associated with a separate product called Upgrade Delta, a hardware-monitoring and remote-management application for Windows and mobile devices. Its end-user licence agreement identifies Velyx Studio as the provider of the software.^[14]

Upgrade Delta collects hardware telemetry for monitoring and diagnostic purposes. Its privacy policy states that the service uses third-party infrastructure including Supabase, Clerk and Lemon Squeezy, while anonymized hardware metrics are sent to OpenRouter/DeepSeek for the service's artificial-intelligence-based Delta Recon diagnostic feature.^[15]

The service's documentation warns that AI-generated diagnostic recommendations may be incorrect or incomplete.^[16]

The use of artificial intelligence by Upgrade Delta has led to some online descriptions of UserBenchmark.org as an "AI" or "vibe-coded" project. Such descriptions are not established facts about the site's development, and the site's documentation only establishes the use of AI for specific diagnostic functionality.

UserBenchmark.org has attracted criticism despite being a new and separate service. Some users have objected to the site's paid-report model, particularly where a benchmark can be run without payment but more detailed results require a purchase.^[11]

Automated website-reputation services have also raised concerns about the domain. Such services have assigned UserBenchmark.org relatively low or middling trust scores based on factors including its recent domain registration and limited reputation history. These automated assessments do not establish that the website is fraudulent or malicious and should not be treated as proof of wrongdoing.

The service's relatively recent appearance, use of the established "UserBenchmark" name, paid detailed reports, and lack of affiliation with UserBenchmark.com have also contributed to confusion between the two websites.

The established UserBenchmark service operates at userbenchmark.com. A similarly named domain, userbenchmark.org, is operated by a separate entity and explicitly states that it has no affiliation with UserBenchmark.com.^[11]

The name UserBenchmarking.com has also occasionally appeared in online discussions as a mistaken or informal reference to UserBenchmark.com. For example, discussions on the Tom's Hardware forums have used the term "userbenchmarking.com" while linking to benchmark results hosted at userbenchmark.com.^[17]

There is no established evidence that UserBenchmarking.com represents a separate major benchmarking service. The terms UserBenchmark, UserBenchmark.com, UserBenchmark.org, and UserBenchmarking.com should therefore not be treated as interchangeable.

As of 2026, the original UserBenchmark.com service remains operational as a user-submitted hardware benchmarking and comparison website, while UserBenchmark.org operates a separate browser-based benchmarking service under the same name.^[8][11]

The two services use different benchmark technologies and publish separate documentation. UserBenchmark.org explicitly disclaims any affiliation with UserBenchmark.com.^[11]

UserBenchmark has remained popular because of its simplicity and large database of user-submitted results. Its benchmark can provide useful information when diagnosing whether a particular computer is performing within the expected range for its hardware.

However, the site's aggregate rankings have been controversial because its scoring methodology is proprietary and has changed over time. The 2019 CPU scoring revision in particular generated substantial criticism because of its effect on the relative rankings of high-core-count processors.^[2]

Professional hardware reviewers generally use multiple controlled workloads rather than relying on a single composite score. Consequently, UserBenchmark results are often best interpreted as one source of performance data rather than as a definitive measure of the relative performance of different CPU or GPU architectures.
